The brunette Russian model will recur on The CW drama as Nadia, one of three recurring characters who will debut on the October 10 premiere. Look for this network-described "emotional chameleon" to be willing to align herself with anyone at any time in order to further what the casting notes outline as a "mysterious agenda."

We will first meet Nadia when she runs into Matt and Rebekah in Prague.

The series is still looking for two more new players, including a college upperclassman who will cozy up to Caroline.
